Carlisle also looks vaguely familiar to Ben - maybe they had talked once on the network? He's almost positive they haven't interacted in person, but he's seen him around and the tired rasp of his voice is not a total surprise. There isn't much room in his mind for curiosity, however. He's here and Pratt trusts him and he can help and that means right now? He is Ben's favorite person.

As Carlisle arrives, Ben gingerly moves that neckerchief - now soaked with blood - so that the healer can see the wounded area. He doesn't pick up on even a flinch. It is easier to be calm with Carlisle acting so calm and straightforward and professional about all this. Which is good, because Ben needs all the calm he can get when he hears what he'll need to do next. He is sure it is necessary and he knows he can do it, but the thought of holding Kieran still, not even letting him scream or move, while he is hurt even more, makes Ben feel a bit sick.

But they don't have time to waste on that. He tightens his grip around Kieran's chest ever so slightly, looking up at Pratt, expression sad and frantic as he asks:

"Can you hold his head still?"

Ben is in a good position to keep the rest of Kieran immobilized, but keeping his head steady will probably be the most important part. He can't do both at once and he can see it in Pratt's body language that he is as desperate to help as Ben is.

Then, to Kieran, he whispers fiercely:

"You can still squeeze my hand but try to stay still. We've got you. You can do this. You're gonna be okay. Everything's gonna be okay."

He tenses up, ready to hold Kieran as still as he can when the healing starts.
